Adjustable Road Marking Nozzle for Uniform Paint Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing road lane marking technologies face issues with durability, slip resistance, and visibility during rain, and are inefficient due to uneven application and the use of large vehicles, which complicates construction and increases accident risks, especially on narrow roads.
Innovation Solution
A road guide line construction apparatus and method that includes a powered painting apparatus with a nozzle system for spraying lane paint and directional marks, featuring adjustable nozzles to ensure consistent application and interval setting, allowing for simultaneous painting of lanes and directional marks with improved visibility and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a fusion type painting apparatus is used to apply lane paint uniformly, then the painting coverage is improved, but the slip resistance and durability are worsened due to hydroplaning in rain
Solution Approach 1:
The patent applies porous aggregate materials in the lane paint composition, which creates a porous surface structure after painting. This porous structure allows rainwater to penetrate through the surface rather than forming hydroplaning films, thereby maintaining slip resistance while achieving uniform painting coverage through the spray application method
2Ease of operation
If a large-sized vehicle with burner and transporter is used for lane marking, then the workability is improved, but the construction flexibility and safety are worsened on narrow roads
Solution Approach 1:
The patent divides the painting apparatus into separable components: a compact spray unit that can be manually moved and a separate paint supply system. This segmentation allows the main spraying mechanism to be small and maneuverable for narrow roads, while the paint supply can be replenished separately, maintaining workability without sacrificing accessibility
Solution Approach 2:
The patent introduces a hose as an intermediary component to connect the manually movable spray unit with the paint supply source. This allows the spray unit to be positioned independently on narrow roads while still receiving paint supply through the flexible hose connection, resolving the contradiction between maneuverability and continuous operation
3Device complexity
If manual transporter movement is used for lane painting, then the equipment simplicity is improved, but the painting thickness consistency is worsened due to non-uniform moving speed
Solution Approach 1:
The patent incorporates a flow control valve in the paint supply system that allows the operator to adjust and maintain consistent paint flow rate regardless of movement speed variations. This feedback mechanism compensates for non-uniform transporter movement, ensuring consistent paint thickness while keeping the overall equipment simple and manually operable

Function Achieved in This Case
The solution enhances the quality and stability of road markings, reduces construction time, minimizes user inconvenience, and decreases workplace accidents by ensuring a consistent and visible guide line, even in rainy conditions, while being suitable for narrow roads.
Implementation Method 1
a nozzle part that is installed in the painting apparatus part and sprays the lane paint supplied from the painting apparatus part to form a guide line for a road including at least one of a directional mark and a lane
Data Source
AI summary
An apparatus is for constructing a guide line for a road. The apparatus includes a painting apparatus part that stores a lane paint, is driven by receiving power, and supplies the lane paint. A nozzle part is installed in the painting apparatus part and sprays the lane paint supplied from the painting apparatus part on a road to form a guide line for a road including at least one of a directional mark and a lane. An adjustment part is installed in the painting apparatus part and adjusts at least one of a location and an interval of the lane paint sprayed from the nozzle part.
